FIELD

The present invention pertains to light source mounting systems; moreparticularly the present invention pertains to a mounting system for alight source usable in place of prior art light sources. While thepresent invention is described with regard to its use as a replacementfor a festoon style bulb, those of ordinary skill in the art willunderstand that the system and method of the present invention enablesthe replacement of other types of prior art light sources.

BACKGROUND

In commercial lighting applications, particularly to illuminate productsin display cases, and many direct and indirect lighting applicationssuch as under-shelf lighting or cove lighting, a series of festoon stylebulbs are arranged in a linear or arcuate array with respect to oneanother. The advantage provided by the linear array of festoon stylebulbs is that the pattern of illumination provided is spread out in asubstantially uniform manner over a predetermined distance.

As shown in FIG. 1, prior art incandescent festoon style bulbs 101 havea central elongated translucent tube with electrically conductive capsor wire loops located on either end. Strung between the electricallyconductive caps or wire loops is an elongated filament which produceslight when the caps or wire loops are connected to a source ofelectrical power. One of the drawbacks of festoon style bulbs is theirservice life. Because replacing festoon style bulbs incurs maintenancecosts there is a need in the art to reduce the maintenance cost ofreplacing festoon style bulbs with a source of light having a longerservice life.

One of the alternative sources of light having a longer service lifewhich has recently become available is the light emitting diode or LED.LED's have a longer service life and use less electrical power thanprior art festoon style bulbs. To make LED's more usable as sources oflight, several companies have developed a set of electrical componentrywhich is combinable with one or more LEDs and will transform thecharacteristics of existing available electrical power into electricalpower useable by the one or more LEDs to emit light energy. However,there has been no system and method for mounting the combination of theone or more LEDs together with the electrical componentry into acommonly used AC powered light fixture.

SUMMARY

The present invention provides a system and method for mounting acombination of one or more LEDs and like supporting electricalcomponentry into a commonly used AC powered light fixture designed forthe mounting of prior art festoon style bulbs.

The mounting system and method of the present invention for acombination of one or more LEDs and the supporting electricalcomponentry for transforming electrical energy received from an existingavailable electrical power source into electrical energy usable by theone or more LEDs to cause the one or more LEDs to emit light energyincludes a LED light source support structure. The LED light sourcesupport structure positions the combination of the one or more LEDS andthe supporting electrical componentry near the electrical power source.Further included in the LED light source support structure is a mountingfor at least one pair of electrical contacts for conducting electricalpower from the existing available electrical power source to thesupporting electrical componentry. Also included within the LED lightsource support structure is a heat sink which conducts heat energy awayfrom the one or more LEDs.

Alternatively, a lens may be mounted to the LED light source supportstructure for modifying the light rays emitted by the one or more LEDs.

In another embodiment individual LED light source support structures aremade rotatably connectable, one with another, using an LED light sourcesupport structure connector.

DESCRIPTION OF THE EMBODIMENTS

As previously indicated the present invention is described with regardto its use with a lighting assembly including provisions for mounting afestoon style bulb 101. However, those of ordinary skill in the art willunderstand that the present invention also has applicability to otherlighting assemblies using other styles of bulbs.

As may be seen in FIG. 1 the prior art lighting assembly 100 made foruse with a festoon style bulb 101 includes a linearly oriented basestrip 102. Extending through the base strip 102 are a plurality ofconnectors 103, 104. It is through the connectors 103, 104 thatelectrical energy is conveyed to a festoon style bulb 101 positionedbetween the connectors 103, 104. The flexible nature of the connectors103, 104 provides for the retention of a festoon style lamp 101therebetween. Other styles of connectors such as U-shaped receptaclesand clips for attachment of wire loops may also be found on prior artbase strips 102.

Because of the desire to use LEDs in the prior art lighting assemblyshown in FIG. 1 a need has developed for a mounting system and methodwhich will allow a light source which is a combination of one or moreLEDs and supporting electrical componentry to be placed betweenconnectors on a base strip 102 such as connectors 103, 104 shown inFIG. 1. This combination of one or more LEDs and the supportingelectrical componentry which causes the LEDs to illuminator forms an LEDlight source assembly.

The mounting system 10 for the combination of the one or more LEDs 12and the supporting electrical componentry 14 for supplying electricalenergy to the one or more LEDs 12 in the LED light source assembly 13 isshown in FIG. 2. Included are the one or more LEDs 12 positioned in thecentral portion of a small circuit board 16 on which the supportingelectrical componentry 14 is arranged, mounted and connected. While acircular array of the one or more LEDs 12 is shown, those of ordinaryskill in the art will realize that other arrays of the one or more LEDs12, such as a linear or an arcuate array, may be used without departingfrom the scope of the present invention. It is the supporting electricalcomponentry 14 on the small circuit board 16 which enables the one ormore LEDS to utilize existing available AC or DC electrical power suchas 120V, 12V or 24V to transform the existing available electrical powerinto either rapidly pulsating DC or the type of DC usable by the one ormore LEDS 12 to emit light energy. In actual practice the electricalcomponentry 14 mounted to the small circuit board on 16 uses a techniqueknown as capacitive coupling; however other techniques or transformingavailable electrical power into a condition that is usable by the one ormore LEDs to emit light energy may be used.

According to the present invention a mounting system and method 10 isprovided which performs three essential functions. First, support isprovided for the LED light source assembly 13. Second, provision is madefor connecting the supporting electrical componentry 14 to connectorswhich supply electrical power. And, third, a heat sink 50 is providedfor managing the heat energy developed by the one or more LEDs 12. Eachof these three functions will be explained in greater detail below.

As shown in FIG. 3 an LED light source support structure 30 is formed toinclude an opening 35 into which the small circuit board 16 fits. ThisLED light source support structure 30 both mounts and positions the LEDlight source assembly 13. The remaining portions of the mounting systemand method of the present invention are built around the foundationprovided by the LED light source support structure 30.

As may be further seen by reference to FIG. 3 a pair of slide-fit typeelectrical contacts 40, 42 have been connected to the electricalcomponentry 14 residing on the small circuit board 16. While slide-fittype contacts 40, 42 are used in the preferred embodiment to engageconnectors of the type shown in FIG. 1, those of ordinary skill in theart will understand that a variety of different type electrical contactsmay be used to effection connection to the small circuit board 16without departing from the scope of the present invention. The twoslide-fit type electrical contacts 40, 42 are sized and positioned topass through and are positioned by openings 32, 34 on either end of thelight source support structure 30. Contacts other than slide-fit typeelectrical contacts may be used by changing the size and configurationof openings 32, 34. Such other contacts will enable use of the mountingsystem to of the present invention with U-shaped receptacles or clipsdesigned for the attachment of wire Loops

Underneath the small circuit board 16, but within the LED light sourcesupport structure 30, is a heat sink 50. Shown in the preferredembodiment is a finned heat sink 50 which uses the flow of ambient airpast fins 52 for the transfer of heat energy generated by the one ormore LEDs 12 through the heat sink 50 to disperse the heat energy to theambient air. While a finned heat sink 50 is shown in the preferredembodiment other types of heat sinks, either air cooled or cooled bysome other medium well know to those of ordinary skill in the art, maybe used. If desired, the heat sink 50 and small circuit board 16 may beformed from a thermally conductive polymer.

Separating the electrical connectors 40, 42 from the finned heat sink 50are a pair of insulator end pieces 52, 54. The insulator end pieces 52,54 are positioned at either end of the heat sink 50. In addition toproviding a pathway for the heat energy generated by the one or moreLEDs the top 56 of the heat sink 50 provides a surface on which the tabs53, 55 extending from the insulator end pieces may rest to hold theinsulator end pieces 52, 54 in position with respect to the openings 32,34 formed on either end of the LED light source support structure 30.

As may be seen in FIG. 3A, the openings 32, 34 may be formed to includean angled side 36. This angled side 36 allows the LED light sourcesupport structure 30 to be rotated with respect to the connectorsextending upwardly from base strip 102. It is by this rotation of theLED light source support structure 30 that the light rays from the oneor more LEDs 12 may be re-directed into an orientation other thanorthogonal to the linearly oriented base strip 102. Those of ordinaryskill in the art will understand that mechanical stops or detents may beused to lock the LED light source support structure 30 in variousangular orientations with respect to the base strip 102.

Optionally, and as shown in FIG. 3, attached to the top of the lightsource support structure 30 is a lens assembly 60. The lens assembly 60is both sized and positioned to intercept and modify the characteristicsof the light rays emitted from the one or more LEDs 12. Shown in thepreferred embodiment is a pillow shaped lens with soft curves. The lensassembly 60 is mounted to the light source support structure 30 by atongue 61 and groove 31 connection. The lens itself may be selected froma variety of available lenses for coloration, redirection or reductionof the light intensity emitted by the one or more LEDs 12. The use ofsuch a lens assembly 60 will also permit the user to cause the lightemitted from the one or more LEDs 12 to be directed to just one side ofthe base strip 102 or symmetrically with respect to the base strip 102as desired.

Thus, according to the present invention, a prior art festoon style lamp101 may be replaced by a LED light source assembly 13 when placed withinthe mounting system 10 of the present invention. This replacement of aprior art festoon style bulb 101 is accomplished by first removing theprior art festoon style bulb 101 from the lighting fixture 102 in whichit is mounted. The prior art festoon style bulb 101 is then replacedwith the structure depicted by reference to FIGS. 2 and 3. Specifically,a LED light source assembly 13 including one or more LEDs 12 andsupporting electrical componentry 14 is positioned within the lightsource support structure 30. Electrical contacts 40, 42 for providingelectrical power to the LED light source assembly 13 are positionedwithin openings 32, 34 at either end of the LED light source supportstructure 30. A heat sink 50 is then put in place underneath the LEDlight source support structure 30 for conducting heat energy away fromthe LED light source assembly 13. The structure as depicted in FIGS. 2and 3 is then put in the place of the prior art incandescent festoonstyle light source 101 within the light fixture 102.

Users may elect to only replace prior art festoon style bulbs with thestructure depicted in FIGS. 2 and 3 as the prior art festoon style bulbsburn out or alternatively users may mix the structure depicted in FIGS.2 and 3 with prior art festoon bulbs to achieve lighting effects onlyavailable by using LEDs.

Shown in FIGS. 4A and 4B is an alternate embodiment 110 of the LED lightsource mounting system of the present invention. Instead of a single LEDlight source assembly 13 including one or more LEDs 12, and supportingelectrical componentry 14, mounted within the LED light source supportstructure 30 are multiple LED light source assemblies 73, 83. To expandthe pattern of light energy emitted from the light source assemblies 73,83, the light source assemblies 73, 83, have been positioned on amounting surface 75 including two or more intersecting planes 77, 79.

Shown in FIGS. 4C and 4D is an embodiment including three substantiallyplanar surfaces 77, 78, 79. Such structure enables the use of three LEDlight source assemblies 73, 83, 93. Those of ordinary skill in the artwill understand that if only one or two LED light source assemblies areused other configurations are possible such as those depicted in FIGS.4E, 4F, 4G and 4H.

Shown in FIGS. 5 and 6 is another embodiment of the LED light sourceassembly mounting system and method of the present invention 210particularly adapted for use with a two wire electrical power source200. The two wires in the two wire electrical power source 202, 204 passthrough LED light source assembly support structure 230. The connectors240, 242 at either end of the small circuit board 16 are sharpened topierce the insulation surrounding the wires 202, 204.

Further included in the LED light source support structure 230 arerotatable mechanical connections 262, 264 located on each end. Therotatable mechanical connections 262, 264 are openings sized to engagepins 269 located within light source support structure connector 268.When pins 269 have passed through openings 262, 264, adjacent lightsource support structures 230 are hingedly connected one to another. Akeeper 270 on the bottom of the pins 269 may be used for securing thehinged connection. The two wires 202, 204 in the two wire electricalpower source 200 pass through spaces 270, 272 in the LED light sourcesupport structure connector 268. Accordingly, a series of light sourcesupport structures 230 may be rotatably connected one to another withLED light source support connectors 268 positioned therebetween.

Those of ordinary skill in the art will understand that LED light sourcesupport connectors 268 may be short as shown in FIGS. 5 and 6 or theymay have an extended length for separating the LED light source supports230 at a distance one from another. By the use of a flexible materialsuch as plastic for both the LED light source support structure 230 andthe LED light source support structure connector 268, the LED lightsource support structures 230 and the LED light sources supportconnectors 268 may be easily put together for assembly into a longstraight or formable string. The result is a formable fixture 300 madefrom a string of LED light source support structures 230 and LED lightsource support structure connectors 268 which may be used for both themounting of a plurality of LED light source assemblies 13 and forminginto one or more substantially arcuate shapes. When a plurality of LEDlight source assemblies 13 are mounted in the formable fixture 300, thecombination becomes a formable light assembly 400.

As further shown in FIG. 6, one or more heat sinks 250 are positionednext to each light source support structure 230 for removing heat energygenerated by the light source.

By reference to FIG. 7 it may be seen that the system disclosed in FIGS.5 and 6 may also be used with self-cooling light sources. In thisembodiment 310 the light source support structure 330 has a twoportions, 333, 335. The upper portion 333 has a top side 334 similar tothe light source support structure 30 described in FIGS. 2 and 3 forpositioning a self-cooling light source and any required supportingelectrical componentry. On the bottom side 336 of the upper portion 333of the light source support structure 330 is an opening providing roomfor any electrical contact needed to make electrical contact with wires202, 204.

The lower portion 335 of the light source support structure 330 is sizedto fit within the open space 331 on the bottom side of the upper portion333 of the light source support structure 330. When in position thelower portion 335 of the light source structure 330 may be used forsecuring an electrical contact with wires 202, 204. The rotatableconnection between adjacent light source support structures 330 is thesame as described in FIGS. 5 and 6

While the light source mounting system and method of the presentinvention has been described above according to its preferred andalternate embodiments, those of ordinary skill in the art willunderstand that numerous other embodiments have been enabled. Such otherembodiments shall be included within the scope and meaning of theappended claims.
